A word invented by Framp Champ Grant a.k.a. Prince of the Southside while under the influence of Tanqueray and Michelob Ultra. Although it was originally a slurred version of "what it do," the word itself lacks a specific definition. However, there is a correct and an incorrect context in which one uses this word, although very few people are able to fully comprehend and correctly utilize the word. Although its origin can be directly traced to Hawaii's main island of Oahu, specifically the Southside, its etymology has roots in the Bay Area of Northern California, and its influence is now felt globally from Hawaii to Washington State to New York to the motherland Japan.
